Quantity sometimes is more important than quality.Lightflow's Global Illumination Engine is the first computer graphics program to merge
the two: previous systems were only spartan and heuristic imitations of reality, which
produced beautiful but inconsistent images, or partial solutions to the diffuse interreflection
equations, which produced realistic results, but worked only in very rare contexts.
The Lightflow Rendering Interface provides a unique
environment for all of the most significant lighting phenomena: an innovative technology allows a fast
computation of the radiative energy transfer among the surfaces, without losing image quality
in the final renderings and without making the user specify complex lighting parameters implicit in
the scenes.

Lightflow's Global Illumination Engine
is capable of computing both caustics due to specular
reflection and radiosity solutions in a few
minutes, even with scenes containing hundreds of
area-lights, thus bringing scientific accuracy
into the world of desktop computing.
These results are obtained through the proprietary
Multiway Light Channels that, unlike previous
systems based on a monolithic structure,
split the complex problem of light transport in
many simpler parts, each treated with ad hoc
algorithms. This always ensures maximal efficiency and
perfect quality.
